I've been trying to find a 'nice' way to preserve one of my partitions
on installation. Specifically, this is the Compaq diagnostics partition
on Proliant servers. I noticed some traffic in the archives for this
list, but the solutions were fairly specific particular hardware. My
kickstart needs to be across a variety of [Compaq] platforms.
After a bit of mucking about, I've settled on the below as my %pre
script to do what I want. It works OK, but was wondering if more
experienced souls could comment on how to improve it, or whether what
I'm doing is more damaging than useful.
By way of synopsis, the pre-script clears all partitions off all disks,
regardless of hardware, excepting any diagnostics partitions (unless
they are in an extended part, which they shouldn't be). It's a pretty
bad kludge, so suggestions welcome. I'm on RH9.
Thanks in advance
